INA115  
Precision  
INSTRUMENTATION AMPLIFIER  
FEATURES  
DESCRIPTION  
● LOW OFFSET VOLTAGE: 50µV max  
The INA115 is a low cost, general purpose instrumen-  
tation amplifier offering excellent accuracy. Its versa-  
tile three-op amp design and small size make it ideal  
for a wide range of applications. Similar to the model  
INA114, the INA115 provides additional connections  
to the input op amps, A1 and A2, which improve gain  
accuracy in high gains and are useful in forming  
switched-gain amplifiers.  
● LOW DRIFT: 0.25µV/°C max  
● LOW INPUT BIAS CURRENT: 2nA max  
● HIGH COMMON-MODE REJECTION:  
115dB min  
● INPUT OVER-VOLTAGE PROTECTION:  
±40V  
● WIDE SUPPLY RANGE: ±2.25 TO ±18V  
● LOW QUIESCENT CURRENT: 3mA max  
● SOL-16 SURFACE-MOUNT PACKAGE  
A single external resistor sets any gain from 1 to  
10,000. Internal input protection can withstand up to  
±40V without damage.  
The INA115 is laser trimmed for very low offset  
voltage (50µV), drift (0.25µV/˚C) and high common-  
mode rejection (115dB at G=1000). It operates with  
power supplies as low as ±2.25V, allowing use in  
battery operated and single 5V supply systems. Quies-  
cent current is 3mA maximum.  
APPLICATIONS  
● SWITCHED-GAIN AMPLIFIER  
● BRIDGE AMPLIFIER  
● THERMOCOUPLE AMPLIFIER  
● RTD SENSOR AMPLIFIER  
● MEDICAL INSTRUMENTATION  
● DATA ACQUISITION  
The INA115 is available in the SOL-16 surface-mount  
package, specified for the –40°C to +85°C tempera-  
ture range.
